FIELD OF THE INVENTION

The present invention relates to the field of network technologies and particularly to a method, device and system for acquiring a web page.

BACKGROUND OF THE INVENTION

When a user accesses a web page via a web client such as the browser, often a number of web pages are required for the display of the contents of the web page being accessed. Presently, there are a few solutions for acquiring and displaying web page data of each web page at the client.

In one solution, a web page accessing request is sent from a client to a server. Upon receiving the request, the server searches a database at a time for all data related to the content to be accessed by a user and performs the pagination of web pages within its memory. Subsequently, according to the page number of the web page that the user desires to access and sent from the client every time, the server provides the user with the web page corresponding to the page number via the client. In this solution, a large amount of memory in the server is occupied if the amount of data of paginated web pages is large, thus lowering the efficiency of the server.

In another solution, a web page accessing request is sent from a client to a server. Upon receiving the request, the server calculates, according to the page number of the web page that the user desires to access, a starting position and an ending position of web page data corresponding to the page number in a database, searches the database for the data between the starting position and the ending position to generate the web page that the user desires to access, and outputs the web page to the user via the client. In this solution, the server searches the database upon each page switching request from the user. Thus, if a large number of users make requests to access web pages simultaneously, the excessively frequent searching in the database by the server can easily lead to an Input/Output (IO) bottleneck in the database.

 DETAILED DESCRIPTION

The invention can be implemented in numerous ways, including as a process; an apparatus; a system; a composition of matter; a computer program product embodied on a computer readable storage medium; and/or a processor, such as a processor configured to execute instructions stored on and/or provided by a memory coupled to the processor. In this specification, these implementations, or any other form that the invention may take, may be referred to as techniques. In general, the order of the steps of disclosed processes may be altered within the scope of the invention. Unless stated otherwise, a component such as a processor or a memory described as being configured to perform a task may be implemented as a general component that is temporarily configured to perform the task at a given time or a specific component that is manufactured to perform the task. As used herein, the term ‘processor’ refers to one or more devices, circuits, and/or processing cores configured to process data, such as computer program instructions.

A detailed description of one or more embodiments of the invention is provided below along with accompanying figures that illustrate the principles of the invention. The invention is described in connection with such embodiments, but the invention is not limited to any embodiment. The scope of the invention is limited only by the claims and the invention encompasses numerous alternatives, modifications and equivalents. Numerous specific details are set forth in the following description in order to provide a thorough understanding of the invention. These details are provided for the purpose of example and the invention may be practiced according to the claims without some or all of these specific details. For the purpose of clarity, technical material that is known in the technical fields related to the invention has not been described in detail so that the invention is not unnecessarily obscured.

With a method for acquiring a web page, a client, a server and a network system including the client and the server which are provided in embodiments of the present invention, when a user accesses a web page via the client, the frequency of searching a database by the server to acquire web page data, the IO occupation of the database, the IO bottleneck of the database, the amount of memory occupied in the server, and the pressure on the server are all reduced. Further, the speed of outputting and displaying the web page for the user by the client are improved, thereby improving the user's experience.

In an embodiment of the present invention, a hidden form for web page data is provided at a client and web page data that is within a particular page number range and associated with a web page currently accessed by a user is cached in the hidden form at the client through configurable data cache rules, so that the frequency of searching a database by a server, the IO occupation of the database and the amount of memory occupied in the server are all reduced. The solution provided in the embodiment of the present invention can reduce the pressure on the server significantly.

The hidden form is described now. The hidden form is not displayed in the browser and therefore is invisible to a user of a web page. The hidden form is used to store non-user input data.

In some embodiments, the hidden form includes Hypertext Markup Language (HTML) source code that is generated after the client obtains web page data through the server, by the client according to the web page data and configuration parameters in a configuration file preset by the client.

The hidden form may be represented by a specific HTML form that includes form elements of an invisible type (a hidden type). Therefore, the hidden form does not need to receive any user input data and is used to store some data returned from the server and used for web page submission. When a user switches from the current web page to another web page, the data cached in the hidden form may also be transferred to the other web page from the current web page.

The data cached in the hidden form is stored in form elements of the hidden type in the hidden form part of the source code of an HTML web page currently accessed by the user. For example, in a form element of the hidden type <input type=‘hidden’ name=‘age’ value=‘12|15|20|17’/> that is used to record a user age, ‘12|15|20|17’ in the value part is the data cached in the hidden form, i.e., the web page data cached at the client.

Technical solutions provided in embodiments of the present invention are described below with reference to the accompany drawings.

FIG. 1A is a flowchart of a method for acquiring a web page according to an embodiment of the present invention. Process 100 may be performed on a client device, using client software such as a web browser that executes on a processor.

At S101, the client receives a user instruction and obtains from the instruction a page number of a web page that a user desires to access.

At S102, based on the page number of the web page that the user desires to access, the client searches a hidden form that is cached in advance at the client for web page data that the user desires to access. The hidden form includes web page data that corresponds to a plurality of page numbers. It is acquired from a server in advance and stored on the client device. In some embodiments, this step includes determining a starting position and an ending position of web page data contained in the web page that the user desires to access within the hidden form, based on the page number of the web page required to be displayed by the user and the preset amount of data contained in each web page. Based on the starting and ending positions, the hidden form is used to find web page data that the user desires to access.

At S103, it is determined whether web page data is found in the hidden form. If web page data is found, at S104, the client generates the web page that the user desires to access using the web page data found in the hidden form. In some embodiments, the webpage is generated by mapping the web page data found in the hidden form to certain preset web page data properties. In the event that the desired web page data is not found in the hidden form cached in advance at the client based on the page number of the web page that the user desires to access, at S105, the client acquires the web page data that the user desires to access from a server.

FIG. 1B is a flowchart illustrating an embodiment of a process for acquiring the desired web page data from a server. Process 105 in some embodiments corresponds to step S105 of FIG. 1A and is implemented on a client device.

At S151, the client sends to the server a web page data acquiring request, which includes the page number of the web page that the user desires to access, the preset amount of data contained in each web page and the amount of data contained in the hidden form;

At S152, the client receives web page data of a plurality of web pages sent from the server, where the web page data includes the web page data contained in the web page that the user desires to access;

At S153, the client updates its own hidden form using the web page data of the plurality of web pages acquired from the server;

At S154, the client searches the updated hidden form for the web page data that the user desires to access according to the page number of the web page that the user desires to access; and

At 155, the client generates the desired web page using at least the web page data found from the updated hidden form.

FIG. 2 is a flowchart illustrating an embodiment a method for sending web page data. Process 200 may be performed on a server.

At 201, the server receives a web page data acquiring request from a client and obtains from the request a page number of a web page that a user currently desires to access, the amount of data contained in each web page and the amount of data contained in a hidden form.

At 202, based on the page number of the web page that the user currently desires to access and the amount of data contained in each web page, the server determines a starting position and an ending position of the web page data corresponding to the page number within a database of the server.

At 203, based on the starting and ending positions of the web page data that the user currently desires to access within the database, the server reads the web page data from the database.

At 204, based on the amount of data contained in the hidden form, the server reads web page data before the starting position and/or web page data after the ending position from the database. In some embodiments, the server reads from the database a certain amount of web page data before the starting position and after the ending position and the amount of web page data read before the starting position is equal to that of the web page data read after the ending position.

At 205, the server sends the web page data read from the database to the client.

Thus, the server sends not only the web page data that the user currently desires to access, but also web page data within a certain range that is associated with the web page data that the user currently desires to access to the client for caching.

After acquiring the web page data of a plurality of web pages from the server, the client displays a web page for the user upon a request from the user and shows on the displayed web page not only the page number of the current web page but also page numbers of certain paginated web pages that are associated with the current page number and provided for user selection, as shown in FIG. 3. Page 7 is requested by the user and page numbers of pages 4-6 and 8-10 are also displayed.

As used herein, a cache hit refers to the case where the client finds the web page data that the user desires to access from the hidden form cached at the client. To increase the cache hit ratio of the web page data in the embodiment, only a certain range of page numbers near the page number of the current web page are displayed in the displaying of page numbers of the paginated web pages and other page numbers can be displayed only when a button of “previous page (or previous item)” or “next page (or next item)” is selected, as shown in FIG. 3. The button of “previous page” refers to a link to the previous page and hides when the current page is the first page. The button of “next page” refers to a link to the next page and hides when the current page is the last page.

As shown in FIG. 3, page numbers of 7 paginated web pages, i.e., page numbers 4, 5, 6, 7, 8, 9 and 10, are displayed on a web page and the page number of the currently displayed web page is 7 because that is the page the user has selected to view. In the present embodiment, page numbers of the paginated web pages that are displayed on a web page and provided for user selection are referred to as a page number window, which always displays a certain range of page numbers. This range is referred to as a window size, which is denoted as windowSize in the discussions below.

In this example, the windowSize is set to 7 in a configuration file, that is, page numbers of 7 paginated web pages may be displayed on a web page and 7 page numbers are always displayed unless there are fewer than 7 pages available. When a user pages through the web pages, the page number of the currently displayed web page is always positioned in the middle of the page number window if 7 page numbers are included in the current page number window in the present embodiment, unless no page or an inadequate number of pages exist before or after the currently displayed page. For example, when the current web page is the first or last page, or when only one page number may be displayed before the current page number (e.g., the windowSize is 7 and the current page number is 2), the current page number cannot be displayed in the middle of the page number window.

The purpose of such a page number window with a fixed length is, on the one hand, to make the web page more pleasing and avoid a disordered display of page numbers due to excessive page numbers displayed on the web page; on the other hand, to eliminate the behavior of “jumping to a page” made by the user, to improve the cache hit ratio. For example, if a user accesses a web page with a page number of 7 and subsequently accesses a web page with a page number of 80, which is very far from the web page with the page number of 7, and because the client cannot cache so much data of web pages from page 7 to page 80, the cached hidden form would become invalid too fast to alleviate the pressure on the server.

In some embodiments, a configuration file (for example, with a file name of pagenation.xml) is provided at the client and used for parameter configuration while the client acquires web page data from the server, stores the web page data in the hidden form and generates a web page using the hidden form. The configuration file includes parameters such as the amount of data that the hidden form can store, the amount of data that each web page can display, the value of windowSize, properties of the web page data (i.e., properties of data displayed on a web page, also referred to as mapping fields of the web page data) and a separator between different data objects for each property in the hidden form (which is also referred to as a data separator of a hidden form field).

An example of the configuration file pagenation.xml is shown in Table 1 below.

TABLE 1   < pagenation id=“user”>   <!-- data source (which is classified as a table and an object, where the table refers to a database table, and the object refers to a JAVA data object List) -->   <type> table</type>   <!-- name of the database or Java data object -->   <name>user</name>   <!-- mapping fields -->   <fields> name, age, sex, country </fields>   <!-- size of cached data, which is denoted as cacheSize and preferably set as a multiple of pageSize -->   <cacheSize>50 </cacheSize>   <!-- size of data displayed on each page -->   <pageSize>10 </pageSize>   <!-- number of displayed page numbers -->   <windowSize>7</windowSize>   <!-- a data separator of a hidden form field -->   <pagenator>|</pagenator>   </ pagenation>

where, <pagenation id=“user”> indicates that a content identifier (i.e., pagenation id) of the web page data that a user desires to access is a user; <type>table</type> indicates that the data source of the content is a database of a server; <name>user</name> indicates a name of the database; <fields> name, age, sex, country</fields> indicates that properties of network data acquired from the database are name, age, sex and country; <cacheSize>50</cacheSize> indicates that the number of data items that the hidden form of the client can cache is 50, with each data item (i.e., a data object) comprising a value of each of the properties of name, age, sex and country; <pageSize>10</pageSize> indicates that 10 data items may be displayed on each web page; <windowSize>7</windowSize> indicates that a page number window displayed on each web page includes at most 7 page numbers; and <pagenator>|</pagenator> indicates that the separator between different values of the same property is “|”.

In some embodiments, an automatic mapping component for mapping data and form is also provided at the client and is used to translate automatically the data to be cached (i.e., the web page data acquired from the server) into web page (HTML) source code in the hidden form according configuration parameters in the configuration file and insert the source code into the web page, so that the web page to be displayed for the user is obtained.

For example, with the automatic mapping component, four fields of name, age, sex and country (i.e., the properties of the web page data) are obtained from the configuration file and mapped to four sets of data (also referred to as data items, each of which includes data objects of the 4 fields of name, age, sex, and country) obtained from the hidden form, to generate contents to be displayed on a web page, which are shown in Table 2 below. Only 4 data items are shown below for the purpose of illustration.

TABLE 2 Name Age Sex Country Jack 12 M UK Kate 15 F USA Jean 20 M France Hans 17 M Germany

The HTML source code of the hidden form is shown in Table 3 below.

TABLE 3 <form name=‘user’ method=‘post’> <!-- the cached data follows --> <input type=‘hidden’ name=‘name’ value=‘Jack|Kate|Jean|Hans’/> <input type=‘hidden’ name=‘age’ value=‘12|15|20|17’/> <input type=‘hidden’ name=‘sex’ value=‘M|F|M|M’/> <input type=‘hidden’ name=‘country’ value=‘UK|USA|France|Germany’/> <!-- the above is the cached data --> <!-- row number of starting data in the cached data within the database follows --> <input type=‘hidden’ name=“startNo” value=‘31’/> <!-- the above is row number of starting data in the cached data within the database --> </form>

where <form name=‘user’ method=‘post’> indicates that a content identifier of the web page data stored in the hidden form is “user”.

As shown in table 3, each of the fields is mapped to a hidden form field and both of the fields have the same name. Values (data objects) of the same field at each row of data in Table 3 are separated by the separator configured in the configuration file. For example, data objects of Jack, Kate, Jean and Hans in ‘Jack|Kate|Jean|Hans’ are separated by the separator “|”.

In the example shown, a starting position (also referred to as a starting row number denoted by startNo) of all the web page data acquired from a server within a database of the server is stored in the hidden form. For example, <input type=‘hidden’ name=“startNo” value=‘31’/> in Table 3 indicates that the first set of web page data cached in the hidden form has a row number (startNo) of 31 within the database of the server.

For example, given the fields of name, age, sex and country in the configuration file, by separating ‘Jack|Kate|Jean|Hans’, ‘12|15|20|17’, ‘M|F|M|M’ and ‘UK|USA|France|Germany’ according to the separator “|”, respectively, various values of 4 hidden form fields of name[ ], age[ ], sex[ ] and country[ ] may be obtained, thereby obtaining the web page contents to be displayed for the user as shown in Table 2.

In the present embodiment, based on the page number of the web page that the user desires to access, the client determines whether the web page data of the web page is stored in the hidden form. If the web page data of the web page is not stored in the hidden form, that is, there is a cache miss and the cache is invalid, the client would request the server to re-query the database and re-generate the hidden form caching the data. In other words, the hidden form is updated.

For example, if the user clicks on page 7, cacheSize (i.e., total capacity of the cache) is set as 50 and pageSize (i.e., size of data displayed on each web page, that is, the amount of data displayed on each page) is set as 10 in the configuration file for pagination (pagenation.xml) and the starting row number startNo in the hidden form is set as 31, then the ending row number endNo (i.e., the row number of the last set of data cached in the hidden form within the database of the server) may be calculated as endNo=startNo+cacheSize−1=31+50−1=80. In other words, the 31th through 80th entries of web page data in the database of the server are cached in the hidden form.

Based on the fact that the page number of the web page to be displayed is 7 and 10 sets of data are displayed on each web page, the client determines that the 61st to 70th web page data entries are to be displayed. Because the position range of [61, 70] falls within the position range of [31, 80] of the hidden form, there is a cache hit and the client does not need to request the server to query the database and can simply extract the desired data from the respective positions in the hidden form.

If the page number of the web page that the user desires to access is 10, the web page data of the web page refers to the 91st to 100th sets of data in the database of the server, which is beyond the cache range of [31, 80] of the hidden form. In other words, the web page data that the user desires to access is not cached at the client. In this case, the cache range of the hidden form needs to be adjusted and the client re-requests the server to query the database and re-generates the hidden form to cache the data received as the query result.

In some embodiments, the range of the web page data to be displayed is positioned in the middle of the cache range. To this end, when querying the database, according to the page number of the web page requested by the user, the server determines the starting and ending positions of the web page data corresponding to the page number within the database, reads web page data within the range from the starting position to the ending position and also reads (cacheSize−pageSize)/2 sets of web page data before the starting position and (cacheSize−pageSize)/2 sets of web page data after the ending position. In an example where cacheSize and pageSize in the configuration file are 50 and 10, respectively, 20 sets of data are read before the 91st set of web page data and after the 100th sets of web page data, respectively. In other words, the server finds the 71st to 120th sets of web page data from the database and sends the same to the client and the client in turn caches these web page data in the hidden form, thus a new hidden form is generated and the cache range is adjusted to [71, 120].
